@group Paper Elements

`paper-button` is a button containing text or an image. When the user touches
the button, a ripple effect emanates from the point of contact.

A `paper-button` may be flat or raised. A raised button behaves like a piece
of paper resting on another sheet, and lifts up upon press. Flat buttons do
not raise up. Add the `raisedButton` attribute to make a raised button.

Example:

    <paper-button label="flat button"></paper-button>
    <paper-button label="raised button" raisedButton></paper-button>

A button should be styled with a background color, text color, ripple color
and hover color.

To style the background, text and hover color, apply the `background` and
`color` CSS properties to the button. To style the ripple color, apply the
`color` CSS property to the `#ripple` element in the button's shadow root:

    /* Style #my-button blue with white text and darker blue ink. */
    #my-button {
        background: #4285f4;
        color: #fff;
    }

    #my-button:hover {
        background: #2a56c6;
    }

    #my-button::shadow #ripple {
        color: #2a56c6;
    }
